Hi! The 3 variables (Day, Month and Year) have to be string (or at least, it works that way!) Assuming following variable names : Date: DATE, Day: DAY, Month: MONTH, Year: YEAR) In the After entry block of the date variable, place the lines below: DAY = day(DATE) MONTH = month(DATE) YEAR = year(DATE) Day, month and year are functions which automatically extract the corresponding values. Note: besste to create string variables, so days / months < 10 will stay the way thay have been entered, (03 will wtay 03 and not 3).

Why is this necessary? I see "LION", upper case and delineated with " ".

How to select "string variables" in Epidata Analysis ?
by epidata-list＠lists.umanitoba.ca 01 May '05

01 May '05

Dear sir, Hello. I am one of Epidata Users around the world. I can not select "string variables" by Epidata Analysis. I am not sure whether the "Epidata Analysis" program can select string variables. For example: Name of my Variable : Outcome and my Options for the variable : cure , death , disabled, unknown I write(or do) the command: select outcome="death" But no selection is done and this is the massage : No records available But I am sure that records are available because I myself have entered them and also EpiInfo software do select them ! Thank you REZA __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Do not test estimation in stratified 2x2 tables (b22)
by epidata-list＠lists.umanitoba.ca 15 Apr '05

15 Apr '05

Persons testing build 22 of analysis should notice that the list of issues to resolve before v1.0 contains the line: "Table command - thorough testing of correctness of estimates and inverting tables." Finalisation of estimation procedures started this week and was not included in build 22. The major new part of the programme in build 22 for testing is: a. All file types should be read properly now. Including files with encrypted fields. b. User defined different table design definitions and other refinements to the output design principles. (further documented with installation). regards Jens Lauritsen Coordinator and initiator of EpiData Project http://www.epidata.dk

Sending Data files by e-mail and continue working

> Hello everybody, > I sometimes get an error message "Error reading record" > when I open an Epidata *.rec file. ......... > I believe, that this error only happens with data files > that I received as email-attachments. My suggestion that in situations where you want to e-mail the rec file to another place, send it as a zip file. Some systems adds one line or a blank line to attachments, so I would: One of a-c. a From tools menu make an archive and send it - preferably encrypted, such that contents are not giving problems if the e-mail gets lost or sent to an inappropriate receiver. b. Save data file(s) etc. in a new compressed zip-file, include current date in filename: AFTER FILE BACKUP F:\backup\distinationdirectory ZIP myzipfile.zip [DATE] END c Save data file(s) etc. in a new encrypted data file, do not include current date in filename: AFTER FILE BACKUP F:\dist_dir ENCRYPT myencryptfile secretword END (Points b and c copied from the help file for EpiData v3.1 Jens Lauritsen EpiData Association
